Nonpharmacologic care of heart failure: counseling, dietary restriction, rehabilitation, treatment of sleep apnea, and ultrafiltration

A Pilot Study on Standardized In-hospital Education About Heart Failure Conducted During the First Days After Decompensation

INTRODUCTION

Education addressed to heart failure (HF) patients constitutes an important element of modern comprehensive treatment programs. The present article demonstrates a novel method of standardized in-hospital education addressed to patients admitted due to decompensation in HF.

METHODS

This pilot study was conducted among 20 patients [19 men, age 63 ± 16 years, NYHA (Classification according to New York Heart Association) on admission (II/III/IV): 5/25/70%]. Five-day education was based on individual sessions conducted using colorful boards demonstrating selected, highly practical elements of the knowledge about HF management, prepared by experts in HF management (medical doctors, a psychologist, and a dietician). The level of knowledge about HF was measured before and after education, based on a questionnaire prepared by the authors of the boards.

RESULTS

All patients experienced an improvement of their clinical status (confirmed by reduced New York Heart Association class and body mass, both P < 0.05). Mini Mental State Exam (MMSE) confirmed that no one demonstrated cognitive impairment. The score reflecting the level of knowledge about HF improved significantly after 5 days of in-hospital treatment accompanied by education (P = 0.0001).

CONCLUSIONS

We showed that the proposed model of education addressed to patients with decompensated HF, conducted using colorful boards demonstrating selected, highly practical elements of the knowledge about HF management, prepared by experts in HF management lead to significant increase of HF-related knowledge.

Interprofessional Treatment of Malnutrition and Sarcopenia by Dietitians and Physiotherapists: Exploring Attitudes, Interprofessional Identity, Facilitators, Barriers, and Occurrence

Purpose

Malnutrition and sarcopenia require dietetic and physiotherapy interventions. In this study, we aimed to compare interprofessional identity of dietitians and physiotherapists, as well as attitudes towards, facilitators and barriers for, and occurrence of interprofessional treatment of malnutrition and sarcopenia by both professions.

Methods

A cross-sectional online survey was distributed from December 4, 2021 until January 31, 2022 through an international online network platform for professionals (LinkedIn). Practitioners working as dietitian or physiotherapist in a healthcare setting were eligible for participation. Outcome measures concerned perceptions regarding shared problem domains, interprofessional treatment, attitudes towards interprofessional treatment, interprofessional identity, facilitators, and barriers. A Chi²-test, Mann–Whitney U-test, and Spearman’s Rho correlation were calculated.

Results

Data from 53 physiotherapists and 48 dietitians were included. Malnutrition is considered a shared problem domain by both professions (U = 1248.000; p = 0.858). While sarcopenia is treated by both professions (U = 1260.000; p = 0.927), physiotherapists consider sarcopenia more often a shared problem domain compared to dietitians (U = 1003.000; p = 0.044). Attitudes towards interprofessional treatment were mostly positive (73%, n = 35 and 87%, n = 46 respectively). Interprofessional identity of dietitians was lower compared to physiotherapists (median = 4.0 versus median = 4.3 respectively; U = 875.000, p = 0.007). This was explained by lower interprofessional belonging (median = 4.0 versus median = 4.8 respectively; U = 771.000, p < 0.001) and lower interprofessional commitment (median = 4.0 versus median = 4.3 respectively; U = 942.500, p = 0.023). Interprofessional identity was correlated with efficient means of communication (r = 0.30, p = 0.003) and bureaucracy (r = −0.21, p = 0.034). Other barriers reported included available time, financial compensation, interprofessional knowledge, and obtaining extra care. Most reported facilitators concerned role clarity, clarity of expertise, and willingness of others to collaborate.

Conclusion

Dietitians and physiotherapists have different interprofessional identities, but both are advocates of interprofessional treatment. Both professions mostly treat malnutrition and sarcopenia individually and have different perceptions regarding sarcopenia as shared problem domain. Facilitators were mainly related to clarity and commitment while barriers were mainly related to resources.

Linoleic acid improves assembly of the CII subunit and CIII2/CIV complex of the mitochondrial oxidative phosphorylation system in heart failure

Background

Linoleic acid is the major fatty acid moiety of cardiolipin, which is central to the assembly of components involved in mitochondrial oxidative phosphorylation (OXPHOS). Although linoleic acid is an essential nutrient, its excess intake is harmful to health. On the other hand, linoleic acid has been shown to prevent the reduction in cardiolipin content and to improve mitochondrial function in aged rats with spontaneous hypertensive heart failure (HF). In this study, we found that lower dietary intake of linoleic acid in HF patients statistically correlates with greater severity of HF, and we investigated the mechanisms therein involved.

Methods

HF patients, who were classified as New York Heart Association (NYHA) functional class I (n = 45), II (n = 93), and III (n = 15), were analyzed regarding their dietary intakes of different fatty acids during the one month prior to the study. Then, using a mouse model of HF, we confirmed reduced cardiolipin levels in their cardiac myocytes, and then analyzed the mechanisms by which dietary supplementation of linoleic acid improves cardiac malfunction of mitochondria.

Results

The dietary intake of linoleic acid was significantly lower in NYHA III patients, as compared to NYHA II patients. In HF model mice, both CI-based and CII-based OXPHOS activities were affected together with reduced cardiolipin levels. Silencing of CRLS1, which encodes cardiolipin synthetase, in cultured cardiomyocytes phenocopied these events. Feeding HF mice with linoleic acid improved both CI-based and CII-based respiration as well as left ventricular function, together with an increase in cardiolipin levels. However, although assembly of the respirasome (i.e., CI/CIII₂/CIV complex), as well as assembly of CII subunits and the CIII₂/CIV complex statistically correlated with cardiolipin levels in cultured cardiomyocytes, respirasome assembly was not notably restored by dietary linoleic acid in HF mice. Therefore, although linoleic acid may significantly improve both CI-based and CII-based respiration of cardiomyocytes, respirasomes impaired by HF were not easily repaired by the dietary intake of linoleic acid.

Conclusions

Dietary supplement of linoleic acid is beneficial for improving cardiac malfunction in HF, but is unable to completely cure HF.

Integrative Medical Care Plus Mindfulness Training for Patients With Congestive Heart Failure

Congestive heart failure (CHF) has a high rate of morbidity and mortality. It is often accompanied by other medical and psychosocial comorbidities that complicate treatment and adherence. We conducted a proof of concept pilot project to determine the feasibility of providing integrative group medical visits plus mindfulness training for patients recently discharged with CHF. Patients were eligible if they had been discharged from an inpatient stay for CHF within the 12 months prior to the new program. The Compassionate Approach to Lifestyle and Mind–Body (CALM) Skills for Patients with CHF consisted of 8 weekly visits focusing on patient education about medications, diet, exercise, sleep, and stress management; group support; and training in mind–body skills such as mindfulness, self-compassion, and loving-kindness. Over two 8-week sessions, 8/11 (73%) patients completed at least 4 visits. The patients had an average age of 57 years. The most common comorbidities were weight gain, sleep problems, and fatigue. After the sessions, 100% of patients planned to make changes to their diet, exercise, and stress management practices. Over half of the patients who met with a pharmacist had a medication-related problem. Improvements were observed in depression, fatigue, and satisfaction with life. Integrative group visits focusing on healthy lifestyle, support, and skill-building are feasible even among CHF patients and should be evaluated in controlled trials as a patient-centered approach to improving outcomes related to improving medication management, depression, fatigue, and quality of life.

Telephone Follow-Up of Self-Care Behaviour after a Single Session Education of Patients with Heart Failure in Primary Health Care

BACKGROUND

Improved self-care behaviour is a goal in educational programmes for patients with heart failure, especially in regard to daily self-weighing and salt and fluid restriction.

AIMS

The objectives of the present study were to: (1) describe self-care with special regard to daily self-weighing and salt and fluid restriction in patients with heart failure in primary health care, during one year of monthly telephone follow-up after a single session education, (2) to describe gender differences in regard to self-care and (3) to investigate if self-care was associated with health-related quality of life.

METHODS

The present analysis is a subgroup analysis of a larger randomised trial. After one intensive educational session, a primary health care nurse evaluated 60 patients (mean age 79 years, 52% males, 60% in New York Heart Association class III-IV) by monthly telephone follow-up during 12 months.

RESULTS

The intervention had no effect on quality of life measured by EuroQol 5D and no significant associations were found between quality of life and self-care behaviour. Self-care behaviour measured by The European Self-care Behaviour Scale remained unchanged throughout the study period. No significant gender differences were shown but women had a tendency to improve adherence to daily weight control between 3- and 12 months.

CONCLUSION

The self-care behaviour and quality of life in patients with heart failure did not change during one year of monthly telephone follow-up after a single session education and this indicates a need for more extensive interventions to obtain improved self-care behaviour in these patients.

Assessing the Quality and Comparative Effectiveness of Team-Based Care for Heart Failure: Who, What, Where, When, and How

Team-based or multidisciplinary care may be a potential way to positively impact outcomes for heart failure (HF) patients by improving clinical outcomes, managing patient symptoms, and reducing costs. The multidisciplinary team includes the HF cardiologist, HF nurses, clinical pharmacists, dieticians, exercise specialists, mental health providers, social workers, primary care providers, and additional subspecialty providers. The timing and setting of multidisciplinary care depends on the needs of the patient and the resources available. Multidisciplinary HF teams should be evaluated based on their ability to achieve goals, as well as their potential for sustainability over time.

Patient experiences of structured heart failure programmes

Objectives. Patient experiences of structured heart failure rehabilitation and their views on the important components of heart failure services were examined. Methods. Focus groups were conducted with fifteen participants (men, n = 12) attending one of two heart failure rehabilitation programmes. Sessions were guided by a semistructured interview schedule covering participants' experiences of the programme, maintenance, and GP role. Focus group transcripts were analysed qualitatively. Results. Participants indicated that rehabilitation programmes substantially met their needs. Supervised exercise sessions increased confidence to resume physical activity, while peer-group interaction and supportive medical staff improved morale. However, once the programme ended, some participants' self-care motivation lapsed, especially maintenance of an exercise routine. Patients doubted their GPs' ability to help them manage their condition. Conclusion. Structured rehabilitation programmes are effective in enabling patients to develop lifestyle skills to live with heart failure. However, postrehabilitation maintenance interventions are necessary to sustain patients' confidence in disease self-management.

Psychosocial and behavioural factors in heart transplant candidates – an overview

Mortality among heart transplant (HTX) candidates remains high. This review of the literature shows that psychosocial characteristics like depression, social isolation and coping strategies contribute to morbidity and mortality in heart failure (HF) patients, and may also be relevant to the prognosis of HTX candidates. Based on the research to date, physical activity favourably affects subjective and objective parameters not only in HF patients, but also in HTX candidates. Depression is prevalent among HTX candidates, especially in ischaemic patients, and seems to be related to earlier transplantation. Findings on the effects of depression on pretransplant mortality are conflicting. Not much is known concerning social isolation, coping, nutrition, or weight loss in this patient group. Identification of modifiable psychosocial and behavioural variables related to clinical status in this patient group is clearly needed and will aid the development of behavioural interventions to supplement medical therapies.

Patient education in heart failure

The preparation of chronically ill patients for self-care has traditionally rested on the assumption that patients require certain knowledge and skills. A review of the literature on the subject of patient education in heart failure suggests that although teaching patients about the care of a chronic condition is necessary, it may be more effective if supplemented by continuing reinforcement, symptom monitoring, and behavioral reinforcement by an interdisciplinary team. Nurses have an opportunity and a responsibility to dissect and test the teaching-learning process in heart failure. Evidence that builds on what is already known about patient education will allow nurses to construct protocols that can be adopted as standards of practice and included in electronic health records.

Novel strategies: challenge loop diuretics and sodium management in heart failure--Part I

This is the first of a 2-part series. This article reviews the relationships among diuretics, neurohormonal activation, renal function, fluid and Na management, the cardiorenal syndrome, and heart failure. Part II will describe novel therapies based on these relationships, focusing particularly on vasopressin antagonists and treatment using hypertonic saline solution with high-dose loop diuretics. Heart failure (HF) is a complex hemodynamic disorder characterized by chronic and progressive pump failure and fluid accumulation. Diuretics are a vital component of symptomatic management, and enhancing diuretic response in the setting of diuretic resistance is therefore pivotal. In HF patients treated with diuretics, compensatory pathophysiologic mechanisms to maintain vascular resistance, such as nonosmotic stimulation of vasopressin secretion and activation of the renin-angiotensin-aldosterone system and sympathetic nervous system, promote renal Na and water reabsorption. Thus, there remains a need to develop novel therapies for HF patients who are refractory to conventional medical treatment. The conflicting results of diuretic treatments in HF and the importance of Na management in the context of the cardiorenal syndrome and neurohormonal activation have suggested novel and counterintuitive strategies, focusing primarily on the use of vasopressin antagonists and hypertonic saline solution with high doses of loop diuretics and neurohormonal interference. The authors review the current evidence for these therapies and suggest hypothetical bases for their efficacy.

Sleep‐Disordered Breathing and the Association With Cardiovascular Risk

Breathing-related sleep disorders, particularly obstructive sleep apnea, have been largely undiagnosed in people with cardiovascular disease, probably due to limited health care provider awareness of the association between the two conditions. Solid evidence is emerging that the apneic events that occur during sleep lead to acute and chronic hemodynamic changes during wake time, including elevated sympathetic tone, decreased stroke volume and cardiac output, increased heart rate, and changes in circulating hormones that regulate blood pressure, fluid volume, vasoconstriction, and vasodilation. Obstructive sleep apnea is associated with known cardiovascular risk factors such as obesity and hyperlipidemia, and is considered by many sleep clinicians to be an independent risk factor for hypertension. Additionally, sleep apnea has been implicated in the pathogenesis of heart failure and stroke. Treatment with positive airway pressure during sleep eliminates the apneic events and the ensuing acute hemodynamic changes. Improvements in daytime blood pressure and left ventricular function also have been noted in persons with hypertension and heart failure. Because effective treatment is available for sleep apnea, this condition needs to be diagnosed and treated in persons with cardiovascular disease.

B-type natriuretic peptide and N-terminal pro B-type natriuretic peptide are depressed in obesity despite higher left ventricular end diastolic pressures

BACKGROUND

B-type natriuretic peptide (BNP) and N-terminal proBNP (NT-proBNP) are frequently used in diagnosing and monitoring patients with heart failure. Recent studies have demonstrated that concentrations of these peptides are decreased in obese patients, but whether lower natriuretic peptide concentrations are really due to different hemodynamics is unknown. The relationship between these markers and left ventricular end diastolic pressure (LVEDP) in obesity has not been elucidated.

METHODS

We examined patients undergoing cardiac catheterization who had creatinine of < 2.0, no evidence of myocardial infarction or pulmonary embolism, and no cardiac transplant. Body mass index and LVEDP were determined, and BNP and NT-proBNP obtained at the start of each case. Obesity was defined as body mass index of > or = 30 kg/m2.

RESULTS

Of 203 patients enrolled, 101 were obese. The groups were similar in respect to race, creatinine, cholesterol, and history of dyslipidemia and cardiomyopathy. The obese patients tended to be younger, were more likely to have diabetes and hypertension, and were less likely to have coronary artery disease. The obese patients had higher LVEDP but reduced BNP and NT-pro-BNP. The relationship between the natriuretic peptides and LVEDP was poor, with r values of < 0.1.

CONCLUSIONS

Obese patients have reduced concentrations of BNP and NT-proBNP compared to nonobese patients despite having elevated LVEDP. This suggests that factors other than cardiac status impact on BNP and NT-proBNP concentrations. The poor relationship between natriuretic peptide concentrations and LVEDP also suggests that these concentrations should not be considered surrogates for cardiac filling pressures or volumes.

Psychosoziale Aspekte und Gesundheitsverhalten bei Herzinsuffizienz

Zusammenfassung. Für die steigende Zahl von Patienten mit Herzinsuffizienz stehen verschiedene medizinische Behandlungsansätze zur Verfügung, darunter als letzte Option die Herztransplantation (HTX). Ergänzende psychosoziale und behaviorale Interventionen erscheinen aus verschiedenen Gründen auch für Patienten auf der HTX-Warteliste sinnvoll. Unser Literaturüberblick zeigt, dass bekannte psychosoziale koronare Risikofaktoren wie Depressivität und soziale Isolation auch bei Herzinsuffizienz Morbidität und Mortalität erhöhen. Körperliche Aktivität wirkt sich dagegen günstig auf subjektive und objektive Parameter aus. Diese Faktoren stellen erste Ansatzpunkte für verhaltensorientierte Interventionen dar. Welche Rolle andere koronare Risikofaktoren (z.B. Feindseligkeit, Ärger, Ernährung und Gewichtsreduktion) spielen, ist bislang ungeklärt. Ausblickend werden einige viel versprechende Forschungsansätze skizziert.

Optimizing treatment and outcomes in acute heart failure: beyond initial triage

Heart failure contributes substantially to health care costs in the United States due to its prevalence and frequent necessity for repeat hospitalizations to manage episodes of acute decompensation. Heart failure overwhelmingly impacts Medicare costs, as the highest proportion of heart failure patients are older than 65 years of age. Efforts to reduce morbidity, mortality, and health care resource utilization have been achieved successfully through emergency department-based heart failure observation units. For select patients, the observation unit can provide care with effective oral agents, including angiotensin-converting enzyme inhibitors, beta-adrenergic receptor blockers, and diuretics, as well as administration of other vasoactive agents, followed by a discharge plan of effective heart failure education and rigorous follow-up management. As advanced pharmacologic and diagnostic therapies continue to emerge, the observation unit staff can play an integral role in the critical education and self-management tools that are needed by the patient to ultimately improve outcomes and quality of life.

Differences between depressed patients with heart failure and those with pulmonary disease

OBJECTIVE

The objective of this study was to examine differences between depressed medical inpatients with congestive heart failure (CHF) and chronic pulmonary disease (CPD) that could impact the etiology and management of depression in this setting.

METHODS

Patients aged 50 years or over consecutively admitted to Duke University Medical Center and three community hospitals were screened for depressive disorder using the Structured Clinical Interview for Depression (SCID-IV). Characteristics of depressed patients with CHF (N = 174) and CPD (N = 527) were compared. Analyses were stratified by type of depressive disorder (major versus minor).

RESULTS

Depressed hospitalized medical patients with CHF and CPD are similar to one another in many respects, particularly with regard to severity of depressive symptoms and shortness of breath. However, patients with CHF in this study had greater medical comorbidity and overall more severe medical illnesses but less severe CHF-specific disease severity compared with patients with CPD. Patients with CPD, however, were more likely to have psychologic risk factors such as a psychiatric history, comorbid psychiatric illness, and stressful life events.

CONCLUSION

These findings suggest important differences between depressed patients with CHF and those with CPD, perhaps reflecting differences in depression etiology and need for specific strategies for managing depression in each of these conditions.

Cardiopulmonary Rehabilitation and Cancer Rehabilitation. 1. Cardiac Rehabilitation Review

Cardiac rehabilitation includes not only the rehabilitation of people with ischemic heart disease but also those with congestive heart failure, heart transplantation, congenital heart disease, and other conditions. New advances in medical treatment have arisen, and there are new approaches in treatment, including alternative medicine and complementary care. New surgical approaches that help restore cardiac function have also been introduced, and rehabilitation professionals must be aware of these advances and be able to incorporate this knowledge into the practice of rehabilitation medicine.

OVERALL ARTICLE OBJECTIVES

(a) To identify major categories of cardiac disease, (b) to elucidate appropriate interventions and support for patients with coronary artery disease, (c) to describe the new interventions available for the treatment of cardiac disease, and (d) to describe the appropriate role of cardiac rehabilitation for people with various forms of cardiac disease.

Impact of symptom prevalence and symptom burden on quality of life in patients with heart failure

BACKGROUND

Heart failure is an escalating health problem around the world. Despite significant scientific advances, heart failure patients experience multiple physical and psychological symptoms that can impact the quality of life.

AIMS

To determine the (1) symptom prevalence, severity, distress and symptom burden in patients with heart failure; (2) impact of age and gender on symptom prevalence, severity, distress and symptom burden; and (3) impact of symptom prevalence and symptom burden on health-related quality of life (HRQOL) in patients with heart failure.

METHODS

A convenience sample of 53 heart failure patients participated in this descriptive, cross-sectional design. Symptoms and HRQOL were measured using the Memorial Symptom Assessment Scale-Heart Failure and the Minnesota Living with Heart Failure Questionnaire.

RESULTS

Patients experienced a mean of 15.1+/-8.0 symptoms. Shortness of breath and lack of energy were the most prevalent. Difficulty sleeping was the most burdensome symptom. Lower age, worse functional status, total symptom prevalence and total symptom burden predicted 67% of the variance in HRQOL.

CONCLUSION

Patients with heart failure experience a high level of symptoms and symptom burden. Nurses should target interventions to decrease frequency, severity, distress and overall symptom burden and improve HRQOL.

Advances in the non-drug, non-surgical, non-device management of chronic heart failure

There have been many articles, reviews and editorials about the recent advances in pharmaceutical and device management of chronic heart failure in this and other journals over the last few years. What has been less praised are the significant advances we have made in understanding the best management of heart failure using other non-drug, non-surgical, non-device approaches. Approaches as diverse as nutrition, education, exercise, physiotherapy, psychotherapy and therapies for sleep-disordered breathing have shown considerable promise in improving the lot of our chronic heart failure (CHF) patients. Chronic heart failure is a common condition with a poor prognosis. It generates many debilitating symptoms for the sufferer. Non-pharmacologic treatment modalities play an important role alongside effective modern pharmaceutical, surgical and device therapies in relieving symptoms and improving prognosis. These treatments include those lifestyle measures that reduce the risk of underlying diseases such as coronary artery disease, diabetes, and hypertension lifestyle interventions of benefit in established CHF. Recent advances are reviewed including specialist nursing care, multi-disciplinary heart failure clinics, exercise rehabilitation, the treatment of sleep-disordered breathing, depression, obesity and cachexia. The day of the multi-disciplinary patient-centred CHF clinic has arrived and all sufferers deserve experienced management using all these approaches.

Heart failure observation units: optimizing care

Heart failure causes substantial morbidity and mortality in the United States and accounts for a higher proportion of Medicare costs than any other disease. Most of these costs result from the high rate of hospital admissions and protracted length of stay associated with episodes of acute decompensation of heart failure. Thus, effective clinical strategies to obviate hospitalization and readmission can result in substantial savings. A specialized heart failure observation unit, in which patients receive rapid, goal-directed emergency care for heart failure symptoms, can be a critical component in this effort, providing intensive therapeutic monitoring and education. In institutions with specialized heart failure observation units, patients are triaged to this setting shortly after presentation to the emergency department (ED), and clinic referrals can be directed to this unit after minimal ED evaluation. Aggressive follow-up is also arranged at discharge. Recent additions to the therapeutic armamentarium and future advances in diagnostics and monitoring will continue to improve patient care and prevent avoidable hospitalizations.

Nonpharmacological strategies for improving heart failure outcomes in the community: a systematic review

The purpose of this systematic review was to synthesize current evidence regarding nonpharmacological approaches to heart failure (HF) management. Following a literature search, identified studies were coded using the Heart Failure Study Assessment Scale (HFSAS) developed by the authors. Results included high-quality ratings, a predominance of multidisciplinary disease management studies, decreased readmission rates, and some improvement in quality of life. Implications for practice, leadership, education, and research are described.

Cardiorenal syndrome in decompensated heart failure: Prognostic and therapeutic implications

Various lines of evidence implicate impaired renal function as an important prognostic indicator in patients with congestive heart failure (CHF). Conventional diuretics may aggravate renal dysfunction and can result in neurohumoral activation. Evolving new therapeutic strategies that enhance renal function include administration of B-type natriuretic peptide, adenosine and vasopressin antagonists, and ultrafiltration methods. Prospective studies are needed to evaluate whether these new renal-enhancing strategies will improve patient outcome in CHF.
